The following figure is a functional block diagram illustrating the main functions:
| PIN# | signal | I/O | Description |
| 1 | VCC_IN | - | 3.3V power input 3.0V ~ 3.6V, power supply must provide 1A or more current |
| 2 | GND | - | Power ground |
| 3 | GND | - | Power ground |
| 4 | LED_DEC_G | O | Decoding green indicator light control signal output; output high/low level control indicator driving circuit, output high indicator light |
| 5 | LED_DEC_B | O | Blue light control reserved pin |
| 6 | Buzz | O | Buzzer control signal output; output PWM signal controls the buzzer drive circuit, when the PWM signal is output, the buzzer emits a “be be” sound |
| 7 | BOOT_SEL0 | I | The main chip working mode switches the pin to work normally when it is high level, and enters the upgrade mode when it is low level, and is reserved for online upgrade |
| 8 | UART_RX0 | I/O | UART data reception |
| 9 | UART_TX0 | I/O | UART data transmission |
| 10 | LED_ILM | O | Fill light control signal output; output high/low level control fill light drive circuit, output high fill light is on |
| 11 | nTrig | I | Trigger key input signal, keep low level for more than 10ms to trigger reading |
| 12 | Reset | I | Reset signal input, active low, keep low for more than 1ms to reset the device |
| 13 | USB_DM | I/O | USB communication D- data signal |
| PIN# | signal | I/O | Description |
| 14 | USB_DP | I/O | USB communication D+ data signal |
| 15 | GND | - | Power Ground |
| 16 | OUT_2V8 | - | Camera 2.8V power supply output, maximum output current 100mA |
